These guys just took Nerf battles to the next level, creating the world’s biggest functioning Nerf gun. Sick of being defeated in office Nerf battles, engineer, Mark Rober and his fellow engineer mates created the the Mega-Maverick.The oversized toy gun uses a 3,000 PSI air tank to fill an 80 PSI reserve cylinder. The darts were created out of pool noodles and toiler plungers. It’s a serious upgrade from a standard Nerf gun, shooting darts at a speed of up to 60 km/h.
